into the machine has been dispensed. The

said means is adjustable, and includes a slotted arm in which a roller in disposed, the roller being mounted on a rack which is operatively connected with the remainder of the said means. The angularity of the slotted arm relatively to the pump plunger to which the slotted arm is secured may be regulated with reference to the price of the fluid, so that the fluid will be shut off when fluid to the value of the coin introduced is dispensed, whether the price of fluid is ten,

twenty, or thirty cents a gallon.

Another object of the invention is to provide means which are operatively connected by a coin for turning on the fluid; for set-' ting a trigger connected with the means for shutting off the fluid, and for connecting means by which the pump plunger is adapted to operate the indicator. The means which is operatively connected by a coin also serves to close a clutch which completes the connection between the rack and the mechanism operated thereby.

Additional objects of the invention are to provide a second indicator which may be disposed at a distance from the machine,

and which will operate step-by-step with the movement of the indicator on the machine; to provide means for closing the coin chutes when all the fluid has been sold, and to provide the chutes with means to reject iron slugs.

Other objects of the invention will appear in the following specification, in which the preferred form of the invention is dis-' closed.

Fig. 9 is an enlarged sectional view on the line 99 of Fig. 2; and

Fig. 10 is an elevation showing, the front of the casing in which the machine is housed.

By referring to the drawings, it will be seen that the-body of the machine is housed in a casing 11, and the pump is housed in a casing 12 which is secured to the side of the casing '11.

A pump 13 has a plunger 14 to which issecured a rack 15 at 16 and 17. Pivoted to 20 is disposed, a nut 21 meshing with this screw and pressing against the slotted arm 19 to hold the arm 19 and thelink 18 in position after the angularity of the slotted link 18 is adjusted relatively to the rack 15 and the plunger 14. There is also pivoted to the slotted link 18 at 22 an arm 23 having a scale or prices 24 indicated thereon, the said scale or prices 2 1 being exhibited through an opening 25 in the rack 15, so that a pointer 26 mounted 'in the opening 25 in the rack 15 will point to one of the marks indicating a position on the scale, or a stated price. This construction is provided so that the' position, of the slotted link 18 may be determined relatively to the rack 15 with reference to the market price of the fluid which is to be sold in the vending machine. For instance, if the price of the fluid which is to be sold should be 30 cents a gallon, the bottom of the slotted link would be very much farther away from the bottom of the rack 15 than would be the case if the market price of the fluid to be sold were 10 cents a gallon, for the supply of fluid is shut off when a rack 27 is moved a predetermined distance, the said rack 27 having a roller 28 which is disposed in the slot in the link 18. When the bottom of the link 18 is disposed at considerable distance from the bottom of the rack 15, the

. to cut off the suppl of fluid not only with rack 27 will be moved to shut off the supply of fluid much more quickly with a predetermined rate of speed of the pump plunger 14 than would be'the case should the bottom of the slotted link 18 be' disposed much nearer the bottom of the rack 15.

The rack 27 is disposed in a horizontal position and slides in guideways 29, the teeth of thesaid rack meshing with the teeth of a gear 30 mounted on a shaft 31. The said shaft 31 leads to a roller clutch 32,

shown in Figs. 4 and 5 of the drawings, this a clutch 32 being of the usual construction, by means of which the shaft 31 may transmit rotary motion to a shaft 33 when the shaft 31- is rotated. in one direction, but which will permit the rotary movement of the shaft 31 in the opposite direction independently of the shaft 33. This construction is provided so that while the pump plunger 14 will transmit motion by the means described to the shaft 33 when the piston plunger 14 moves in one direction, the return movement of the piston plunger may take place without rotating the shaft 33. A friction clutch member 34 is mounted on the shaft 33 and rotates therewith, this friction clutch member 34 .bein adapted to engage a friction clutch mem er 35 secured to a shaft 36 which has a gear 37, meshing with a rack 38 secured to the rear of the plate- 39. Mounted on the plate 39 there are pins 40, 41, 42, 43, and 44, the pin 44 being disposed adjacent the top of the plate 39, in line with a rack 45; the pin 43 being disposed at a greater distance from the top of the plate 39 and being in line with a rack 46; the pin 42 being disposed a still greater distance from the top of the late 39 and in line with the rack 47; the pin 41 being disposed approximately an even distance between the top and the bottom of the plate 39 and in line with a rack 48, and the pin 40 being disposed adjacent the bottom of the plate 39 and in line with a rack 49. These pins 40, 41, 42, 43 and 44 are disposed in this manner so that they will serve reference to the mar et price of the fluid, but also with reference to the value of the coin which is introduced in one of the coin slots, there being five coin slots corresponding with the pins 40, 41, 42, 43 and 44 and the racks 45, 46, 47, 48 and 49. A coin slot 50 is used for 5-cent pieces, and the pin 44 on the plate 39, in connection with the means which I will shortly describe, is disposed to cut off the supply of fluid when 5 cents worth of the fluid at the current price has been dispensed, the slotted link 18' having been adusted with reference to the market price. A coin slot 51 is provided for 10-cent pieces, and the pin 43 is provided to cut off the supply of fluid when 10 cents worth of the fluid worth has" has been dispensed. In a similar manner coin slots 52, 53 and 54 are provided for 25-cent pieces, 50-cent ieces, and silver dollars respectively, the plus 42, 41 and 40 being provided to cut off the supply of fluid when 25 cents worth, 50 cents Worth, or a dollars en dispensed.

Each of the coin slots 50, 51, 52, 53 and 54 is constructed in the same manner, and I will therefore describe only one of the said coin slots, with the mechanism connected therewith. By referring to Fig. 7 of the drawings, it will be seen that the coin chute 54 leads to a finger 55 disposed below a shoulder 56 on a rod 57 so that when a coin 58 rolls down the coin slot 54 and rests on the finger 55, the coin will be disposed between the finger 55 and the shoulder 56, the bottom of the shoulder 56 and the top of the finger 55 converging slightly awa from the .coin chute, to hold the com 58 1n this position. An arm 59 is secured to a shaft 60 to which there is also secured a gear wheel 61, there being on this gear wheel 61 a pin 62 which when the gear 61 is rotated engages an arm 63 secured to a shaft 64, to which the finger 55 is also secured so that when the shaft 60 is rotated it willrotate the gear 61, and with it the pin 62, and the pin 62 will engage the arm 63 to rotate the shaft 64, thereby raising the finger 55, which presses the coin 58 against the rod 57 upwardly sufficiently far to bring the rack teeth 65 on the rod 57 into mesh with the gear teeth on the gear 61. It will be understood that when the arm 59 is rotated further the rod 57 will be raised by means of the engagement of the teeth on the gear 61 with the rack teeth 65.

The shaft 60 extends across the machine, and there are five gears 61 mounted on the said shaft, and there are five sets of fingers 55 and arms 63, one of the fingers 55 being disposed adjacent the bottom of'each of thev coin chutes 54. The five rods having shoul ders 56, are shown in Fig. 1 of the drawings as numbered 57, 57, 57", 57, and 57 lVhen one of these rods 57, 57, 57, 57, or 57 is raised, it pushes against one of the cams 66 on a shaft 67, to rotate the said shaft 67, this shaft 67 having a crank 68, to which is articulated a link 69. This link 69 is connected with a valve 70 at 71. There is also secured to this link 69 at 72 an arm 73 of a lever 74 which is pivoted at 7 5, and which has rollers 7 6 disposed in an annular groove in a part of the clutch member 34 to operate the said clutch member. It will, therefore, be seen that when-the coin is introduced in one of the slots, and the arm 59 is rotated to rotate the shaft 60, the rod'57 will press up on one of the cams 66 to rotate the shaft 67, by which means the valve 70 will be opened to' an outlet, and the clutch member 34 will be pressed into engagement with the clutch member 35. This will not only open the outlet so that the fluid may be dispensed when the pump is operated by means of a handle 77, in a manner readily understood, but it will also by the engagement of the clutch member 34 with the clutch member 35 cut ofi the supply of fluid when the proper amount has been dispensed with reference to the value of the coin which has been introduced in the coin slot in the machine, for with the rotation of the clutch member 35 and the shaft 36, the plate 39 will be raised in the manner which has been described, and one of the pins 40, 41, 42, 43, 44 on the plate 39 will engage a trigger which I will now describe, to shut oif the flow of the fluid.

There is secured to the rear of each of the rods 57 a trigger 78, the bottom of which is shown clearly in Fig. 9 of the drawings, the bottom of each. trigger 78 being disposed through an opening 79 is a support 80, and there being springs 81 at the side of each opening 79 for moving the trigger 78 laterally when it is raised, so that it will rest on the support 80 at its shoulder 82, and remain in this position until one of the pins 40, 41, 42, 43, 44 en ages a cam surface 83 at its bottom to pus the trigger 78 back to a posi tion where it may move downwardly in its opening 79 to normal position,

When the rod 57 is raised by means of the gear wheel 61, the trigger 78 will be supported by its engagement at its shoulder 82 with the support 80, and it will remain in this position until its lower end is pushed back into a position where it may again slide downwardly in its slot 79 in the support 80. This will again rotate the shaft 67 to operate the link 69 to move the clutch member 34 away from the clutch member 35, and to close the outlet of the valve 70. If desired, aspring may be mounted on the shaft 67 to assist in this return movement. When th clutch member 34 has been moved away from the clutch member 35, the plate 39 will move downwardly in its guides 84.

As a means to prevent a person from hold.- ing one of the rods 57 up after it has been raised by means of the arm 59, I prefer to cut theshaft 60 and separate the arts by a clutch 85, so that by means of a ever 86 I can move one part of the clutch 85 away from its, companion part, and thereby cut off communication between the arm 59 and the gear 61.- Secured to the plate 39 there is a cam rod 87 which engages the lever 86 to move one part of the clutch 85 away from its companion part as soon as the plate 39 moves upwardly a short distance.

The rack '15 meshes with a gear wheel 88 mounted on a shaft 89 which is connected with a roller clutch 90 similar to that shown in Figs. 4 and 5 of 'the drawings, by means of which the shaft 89 is adapted to rotate a clutch member 91 in one direction, but is prevented from rotatin the said clutch member in the opposite direction. With th s roller clutch 90 and clutch member 91, is adapted to be engaged a companion clutch member 92 as a means for rotating a dial 101, this dial 101 being rovided to indicate the amount of fluid w ich has been dispensed and the amount of fluid still contained in the tank. The clutch member 92 slides up and down out of and into engagement with the clutch member 91, and it is operated in a manner readily understood, by means of a lever 93 fulcrumed at 94, and to which a link 95 is articulated, this link 95 being articulated to an arm 96 secured to the shaft 67. When one of the rods 57 is raised to rock the shaft 67 by means of a cam 66, the shaft 67 not only serves to move the rod 69 to throw the clutch member 34 into engagement with the clutch member 35 and to open the outlet of the valve 70, but it also serves by means of the arm 96, the link 95 and the lever 93, to move the clutch member 92 down into engagement with the clutch member 91. The clutch member 92 rotates with a shaft to which a gear 97 is secured, this gear 97 meshing with the teeth 98 on the dial plate 101, the dial plate 101 having numbers or characters 99 thereon which show one at a time through an opening 100 in the casing 11, to indicate the amount of fluid which has been dispensed, as the dial 101 will rotate with each operation of the pump.

Secured to the rear of the dial 101 there is a ratchet wheel 102 which is engaged by a pawl 103 on a lever 104 fulcrumed at 105, a second lever 106 being articulated to the end 107 of the lever 104. The lever 104 is held yieldingly in position b means of a spring 108 and the lower on of the lever 106 is held yieldingly against a stop 109 by means ofa spring 110 which connects the upper ortion of the lever 106 with the lever 104. he lever 106 has a shoulder 111 which, when the lever 104 is moved by the movement of the pawl 103 over one of the ratchet teeth, will pass below a spring contact member 112, so that the return movement of the lever 104 will raise the lever 106, and the shoulder 111 thereon will engage the end of the spring contact member 112 to move the said spring contact member into engagement with a companion contact member 113. This will momentarily close the circuit 114 having a battery 115, there bein a solenoid 116 in this circuit at any desired distance. When the solenoid 116 is energized by the closing of the circuit, it will act movement of the ratchet wheel 102. The lever 118 is held yieldingl in position by means of a spring 121, an the pawl 119 is held yieldingly in position on the lever 118 by means oi a spring 122. Secured for rotating with the ratchet wheel 120 there is a dial 123 which corresponds with the dial 101, the purpose of this arrangement being to enable the proprietor at a dlstance from the machine to keep track of the quantity of fluid dispensed b the machine and the quantity of fluid stil remaining in the machine.

Each of the coin chutes 54 has an opening 124 therein, a movable section 125 being pivoted at 126 for closing this'opening. A spring 127 is provided for holding the Section 125 in normal position, as mdicated in Figs. 7 and 8 of the drawings, there being disposed below the section 125 a magnet 128 which when an iron slug is rolled into the chute 54 will serve to upset the section 125, inasmuch as the magnet 128 will draw the iron slug downwardly, and as the lower edge of the iron slug will press against the edge 129 of the coin chute section 125, it will cause the section 125 to rotate. The rotary movement of the section 125, together with the'upturned ,edge 129 of the section, will throw the iron slug clear of the magnet 1.28, so that it will be out of the way.

As a means of closing the coin chutes when all the fluid has been dispensed, I provide the dial 101 with a projection 130,

which when the dial 101 rotates to a predetermined position, will engage a crank arm 131 on a rock shaft 132 journaled in bearings 133, this rock shaft 132 having another crank arm 134 which will press a trigger 135 against the resiliency of a spring 138, so that a shoulder 136 on the trigger 135 will be moved clear of a stop 137 and a shutter 139 will be moved downwardly under the influence of springs 140, this shutter 139 moving to a position at the rear of the coin slots to close the latter.

The coin from the finger 55 passes to a vertical coin chute 141, and then to a coin chute 142, the end 143 of which is turned up to hold a predetermined number of coins on the chute 142, the coin at the end 143 of the chute being pushed off when a coin rolls against the said predetermined number of coins on the chute 142. There is a glass window in the frame 11, through which the said coins on the chute 142 may be examined.
